Automation involves setting up devices to trigger one another. You can utilize the latest smart gadgets to enhance your daily routine, for instance, blinds opening at a particular time to start your morning which triggers certain lights to turn on around your house. All home automation devices are Internet of things (IoT) devices, and many of these IoT devices have sensors that monitor changes in motion, temperature, and light so the user can gain information about the device’s surroundings.

Home Automation

Automation involves setting up devices to trigger one another. You can utilize the latest smart gadgets to enhance your daily routine, for instance, blinds opening at a particular time to start your morning which triggers certain lights to turn on around your house. All home automation devices are Internet of things (IoT) devices, and many of these IoT devices have sensors that monitor changes in motion, temperature, and light so the user can gain information about the device’s surroundings.

Automata theory is a cutting-edge theoretical branch of computer science. The word automaton, derived from “automation” and “automatic”, refers to processes that automatically execute to create specific procedures (Hasan, 2022). Automatons are abstract models of machines that perform computations on input by moving through a series of states or configurations (Engati, 2021). A transition function determines the next configuration for each state based on a finite portion of the present configuration. As a result, it accepts that input once the computation reaches an accepting state. There are four major families of automaton:

• Finite-state machine (FSM)

• Pushdown automata (PDA)

• Linear-bounded automata (LBA)

• Turing machine

For this project, you will design and implement an FSM to model the automation of a living room. Using FSM, the programming is simplified, but it creates a flexible, robust system to manage all aspects of the automation process. The FSM is an abstract machine that can be in exactly one of a finite number of states at any given time. It can change from one state to another in response to some inputs; the change from one state to another is called a transition. An FSM is defined by a list of its states, its initial state, and the inputs that trigger each transition. There are two types of FSMs: deterministic finite state machines, often called deterministic finite automata (DFA), and non-deterministic finite state machines, often called non-deterministic finite automata (NFA).

Automation Detail

Three entities in the living room will require automation: window, air conditioner (AC), and lamp. The initial state of the window is closed, and the initial state of the AC and lamp are both off. The window’s state can be opened if a person is detected in the room, and it is daytime. It then closes if no one is detected in the room, AC is on, or it is nighttime. The AC should only turn on if a person is detected in the room and the temperature is hot (80 degrees or higher). It turns off when no one is detected in the room, the window is open, or the temperature is cold (32 degrees or lower). Light switches on when a person enters a room, and it is dark (note: dark does not have to be night). It switches back off if a person is no longer detected or the surrounding is bright.
